Nitrogen fixation and nitrate-reduction activities were determined in photoautotrophic cultures of two wild-type strains of cyanobacterium Nodularia, spp. M1 and M2. Air could support growth of the two strains at a similar rate in the presence or absence of exogenous nitrate, ammonium and/or bicarbo

Depth profiles of nitrogen fixation (acetylene reduction), sulphate reduction, NH4 concentration and porewater volatile fatty acids concentrations were measured in Zostera noltii colonised sediments in the Bassin d'Arcachon, France in March 1994 . Acetylene reduction activity (ARA) was detectable th
Cytochromes c3 of different strains of sulfatereducing bacteria have been purified and tested for their capacity to reduce colloidal sulfur to hydrogen sulfide. The results are in good agreement with the activities reported for the whole cells. Cytochrome c3 is the sulfur reductase of some strains o
